Understanding the Sharpe Ratio
The Sharpe ratio measures the performance of an investment compared to a risk-free asset, after adjusting for its risk.
How It's Calculated
Sharpe Ratio = (Rp - Rf) / σp
Rp = Return of portfolio
Rf = Risk-free rate
σp = Standard deviation of portfolio
This formula helps investors understand whether a portfolio's returns are due to smart investment decisions or excessive risk. A higher Sharpe ratio indicates better risk-adjusted performance.
